Brushing your teeth isn't hard. And the sooner you learn to brush right, the sooner you can have a beautiful, shiny smile that you'll keep for the rest of your life. Here's how to do it:   Brushing With a Regular Toothbrush Make sure you have the right size toothbrush for your mouth. A brush that is too small won't do a good job, and a brush that's too big might hurt your mouth. Also, you should make sure to use a soft bristle brush. Most toothbrush packages have the age written on them. Hold the brush at an angle, so the bristles point toward your gums. This helps clean along the gumline where plaque builds up. Move the brush in small circles, like you're trying to clean each tooth individually. That way you can make sure every single tooth is getting brushed well. Make sure you brush the insides of your teeth as well as the outsides. Brushing only the outsides is like washing only one hand. Tilt your toothbrush when cleaning the inside of your front teeth. Remember to brush in small circles. Don't forget to brush the biting surface of your teeth really well, using a back-and-forth motion. This helps get all the gunk that's trapped in your teeth. Get a new toothbrush about every three months.   Brushing With a Power Toothbrush If you're brushing with a power toothbrush, make sure a grown-up is there in case you have any questions. The cool thing about power toothbrushes is that they do a lot of the brushing for you. Always bring the brushhead to your teeth before turning it on so you don't splash. Move the brushhead from one tooth to the next. Hold the brushhead in place for a few seconds before moving on to the next tooth. Make sure you brush your gums as well as your teeth. Start with the outsides of your teeth, then the insides, then the part that chews your food. Don't press too hard or scrub just let the brush do all the work. Get a new brushhead every three months.
